CHARLES ARTHUR CHAPMAN, OF HORLEY, ENGLAND, ASSIGNOR TO ALFRED WARREN AND CHARLES FIPPARD, OF SAME PLACE.

SPRING-SEAT.

srnorrronrron forming part of Letters Patent No. 610,960, dated September 20, 1898.

Application filed September 20,1897. Serial No. 652,405. (No model.) Patented in England March 26, 1897, No. 7,866g in France August 12, 1897, No. 269,562, and in Austria September 6,1897, No. 47/3363.

To all whom it may concern;

Be it known that I, CHARLES ARTHUR CHAP- MAN, a subject of the Queen of Great Britain, residing at Glenthorne, Horley, in the county of Surrey, England, have invented certain new and useful Spring-Seats, (for which I have received Letters Patent in Great Britain, No. 7,866, dated March 26, 1897; in Aus tria, No. 47/3363, dated September (5, 1897, and in France, No. 269,562, dated August 12, 1897,) of which the following is a specification.

This invention relates to spring-seats especially suitable for the saddles of cycles.

The saddle consists of front and back plates connected by springs which form the seat, each plate being supported by a curved bar having one or more knuckle-jointed hinges in it so arranged that the ends cannot be turned upward beyond a certain point by the tension of the springs, but can be turned downward by pressure, so further stretching the springs.

Figure l is a vertical central section. Fig. 2 is a plan; and Figs. 3 and 4 are transverse sections on the lines 3 3 and a 4., Figs. 1 and 2, looking to the left and right, respectively. Fig. 5 is a local section on the line 5 5, Fig. 1.

a and b are the back and front plates, carried by arms a and b, fixed to them and pivoted, respectively, at a b to the flanges c c of the plate 0. The four corners of each flange c are turned outward,forming stops 0 which limit the movement of the arms a and b. The plate 0 rests on a plate d, the flanges cl of which are notched and rest on the usual bar-support e, the whole being secured by the eyebolt f and nut f.

g is an india-rubber cord covered with braiding and laced around pulleys h on the plates Ct and b. The pulleys h on the plate a. are arranged on the under side thereof near its inner edge. The drawings show eight such pulleys arranged in a curved line beneath the plate. The pulleys h on the plate I) are arranged as indicated in Fig. 4. One pulley at the top of the U-shaped frame is arranged on a vertical axis. The other pulleys are arranged in vertical series on horizontal axes, each horizontal shaft bearing two pulleys. The peak is covered with leather j, and the seat may also be covered with soft leather or other material.

The details of construction may be varied without departing from my invention; but the parts g should be elastic or stretchable, and one at least of the arms a orb should be pivoted.

I Wish it to be understood that I do not claim, broadly, a saddle having a seat consisting of stretched springs; but

What I claim is- 1. In a saddle, the combination of front and back plates, supports for the plates, a joint between the supports so that the plates can move apart, pulleys pivoted to the plates and springs placed around the pulleys.

2. In a saddle, the combination of front and back plates, supports for the plates, pivots for the supports, stops limiting the'travel of the supports, pulleys pivoted to the plates, and india-rubber cord laced around the pulleys.

CHARLES ARTHUR CHAPMAN.
